摘　　要：索道桥以其优美的外形被用于景区人行桥梁,结合实际工程对景区桥梁的设计方案从周边环境、使用功能、施工技术及社会经济效益等多方面进行综合比选,并对人行索道桥的设计从主要构件的设计构造特点、受力特性、施工方法和行人舒适度方面进行分析研究。结果表明,结构上采用双侧均匀布置主索的方式改善了结构受力体系,安装TMD阻尼器方法可有效解决人桥耦合振动问题。Cable suspended bridge is applied to pedestrian bridges in scenic spots for its beautiful appearance.Combined with practical projects,this paper comprehensively compares and selects the design scheme of bridges in scenic spots from the aspects of surrounding environment,using function,construction technology,social and economic benefits.The design of pedestrian cableway bridge is analyzed and studied from the design and structural characteristics,stress characteristics,construction methods and pedestrian comfort of main components.The result shows that the structural stress system is improved by evenly arranging the main cables on both sides,and the problem of pedestrian bridge coupled vibration can be effectively solved by installing TMD damper.
